Massive land development in Phuket province will be strictly controlled by environmental regulations after findings that large amounts of sediment caused by construction has destroyed a large area of coral reefs and marine ecosystems.

Over 250 square kilometres of coral reef surrounding Phuket's Tang Khen Beach had been covered by a massive amount of sediment from land development, according to a study by Phuket Marine Biological Centre.

It said that previously over 250 rai of coral reef at the end of Cape Panwa's Ao Tang Khen was alive. However, coral reefs, particularly staghorn corals, had been totally destroyed. It was now covered by a large amount of sediment - from the seaport and building of three hotels in the area.

There has been massive land development in coastal areas of Phuket over the past five years. Over 100 areas on the coast and mountains, especially western beach areas such as Patong, Ka Ta, Karon and Kamala, were opened and dredged to build resorts.

The large number of building and land projects would hit marine resources, particularly coral reefs around Phuket province, which is a top destination for tourists around the world.

Niphon Pongsuwan, a coral expert who conducted the study, said he was worried the removal of land surfaces in mountainous and coastal areas would accelerate the amount of sediment flowing into the sea, harming reefs and aquatic animals and plants.

His team is now monitoring the changing of coral reefs and marine ecosystems, especially "at risk" areas such as Patong, the north of Ka Ta, the eastern part of Phuket, and Koh Rad.

An evaluation will be conducted every six months. Preliminary investigation results have found that staghorn coral can no longer live there due to the changing marine ecosystem.
